Serialization error with JSON session serializer #17

When using password policies, I get the following error when trying changing the password:

Traceback (most recent call last):

TypeError: datetime.datetime(2014, 8, 14, 17, 57, 53, 151293, tzinfo=<UTC>) is not JSON serializable

The password changes, but I get the error because of the json session serializer. When I change the following setting on settings.py:

SESSION_SERIALIZER='django.contrib.sessions.serializers.PickleSerializer'

I gess it should be in the docs.

It should. Sorry for the delay, but my work took all my attention, even on weekends... just wanted to let you know that the project is not dead... I'll take care of this soon...
